Dosing Calcium Sulfate (CaSO4)

In my planted tank I seem to be having a Calcium deficiency. A lot of the leaves are twisted and curling (new and old growth but more of the old than new)

My question is how much should I dose for a 55 gallon tank which is heavily planted? (also dosing EI) I'm not to familiar with the effects of Calcium besides an aid for plants.

My kH is 4 and gH is 5. This is the same as my tap and would not like this to be effected if possible.

It seems strange that you are diagnosing a calcium deficiency, despite having a gH of 5.

I would think it might be some other deficiency...perhaps someone else has some thoughts on this?
